Vocabulary:

---

earthquake: Is the shaking and trembling that results from the movement of rock beneath the Earth's hard surface.

stress: A force that acts on rock to change its shape or volume.

shearing: Stress that push a mass of rock in two opposite directions.

tension: A force that pulls on the crust, stretching the rock so that it becomes thinner in the middle.

compression: It is a force that pushes rock together, making it higher in the middle.

strike-slip fault: A fault made by shearing.

normal fault: Faults from tension inside of Earth's crust.

reverse fault: Compression produces reverse faults.

mountain building: Made by normal faults.

deformation: It is when there is a change in shape or volume in the Earth's crust.

fault: When Earth's crust breaks and slabs of rock slip past each other.

hanging wall: A block of rock that forms the upper half in a fault.

fault-block mountain: A mountain that was formed under a normal fault that has uplifted a block rock.

folds: After Earth has been compressed, a bend of rock forms where the compressed place was.

syncline: After compression in Earth's crust that causes a downward fold in rocks.

plateau: A landform that has more or less land level with and is higher than sea level.

Outline

---

• Types of stress
  • Shearing
    • Pushes rocks in opposite directions
    • Causes rocks to break
    • Causes rocks to slip apart
    • Causes rocks to change shape
  • Tension
    • Stretches rock: thin in middle
    • Like pulling on warm gum
    • Occurs: two plates moving apart
    • Stress force
  • Compression
    • Squeezes rock
    • Rock will fold or break
    • One plate will push another
    • Like giant trash compactor(Rock)
  • Deformation
    • Earth's crust changes volume/shape
    • Crust changes slowly
    • Speed time=change in deformation(to see)
    • Crust: bend, stretch, tilt, fold, or slide
• Kinds of fault
  • Strike-slip fault
    • Shearing causes Strike-slip faults
  • Normal fault
    • Tension forces causes Normal faults
  • Reverse fault
    • Compression causes Reverse faults
• Faults
  • Hanging wall
  • footwall
